NEMO 101

Portable power quality analyser - 2 voltages (L-N, PE-N) input and 2 current inputs - nominal current rate can 16A.

NEMO 101 is a portable multifunctional power meter and power analyser with datalogger function. It is suitable for comfortable measurement of low voltage instruments directly in the outlet. The combined voltage/current probe is embedded in the plug and can measure up to 16 A current on phase and neutral wire.

NEMO 101 data logger can store months of typical measurements and it also records all disturbance data, log, electricity meter readings (load profiles) and other critically important information for electricians and power quality/energy efficiency professionals.

    Extension firmware modules

  • HDO module: NEMO data loggers can optionally record means signal (ripple control signal, RCS). This enables the instrument to record, decode and store known formats of such remote controll messages.
  • GO module: NEMO data loggers can optionally detect disturbances and record full oscilographic data of 4 voltages and 4 currents into the memory. Condition, pre-triger, length of record and the total capacity on the internal flash disk can be specified.
